Both the obvious options fail. Deleting it directly, or click on it then click delete in the pop up window. In both cases, the links to the websites are still floating around in the Website power up rem, they are just no longer referred to by any rem. And they can’t be deleted in batch either.
The only way to remove a link is to go to individual rem tagged with Link in Website rem, click delete. Then get an error
something went wrong. TypeError: Cannot read properties of undefined (reading ‘_id’)
Then refresh. Rinse repeat 100 times if you have 100 links. lol
